This is for my 92 cherokee with 3 inch lift. I am pulling the engine to swap in a newer one,and wanted to lower the transmission so i could reach the top 2 e12 bolts for the engine/transmission. well,I only got one of the crossmember bolts off before I quit for the day because it broke off flush with the "frame". what can i do to stop the other ones from breaking off? can i get pb blaster into the framerails and let it soak for awhile? what about the broken bolt? I guess i will have to try to drill it out and tap it with a bigger tap,right? I really don't want to cut up the "frame" or floor boards if i can avoid it. thanks
